Ciesco Sector Insights: AI and the Agency Model

AI is reshaping how marketing agencies create and capture value: driving operational efficiency, redefining content production, and elevating the strategic importance of brand counsel. For founders, investors, and agency leadership, the implications are immediate and the window to act is narrow.

In this latest Sector Insights piece, the Ciesco team in collaboration with Craig Lynch, Associate Director at CIL, explore the key trends shaping the marketing services landscape:

• AI Efficiency as Table Stakes: Adopting AI tools and workflows is becoming essential for all marketing businesses, with larger groups better positioned to leverage economies of scale and proprietary IP.
• Content Production Bifurcation: AI is well-suited to templated, high-volume content, but high-end, brand-defining work is expected to remain human-led, repositioning premium and full-service agencies favourably.
• The Flight to Quality: As AI-generated content proliferates, brands will increasingly invest in brand strategy and identity. Services that rely on human judgement and senior counsel, and are resistant to AI disintermediation.
• Winning Commercial Models: Leading agencies are shifting to output-based pricing and building full-service capabilities through targeted M&A, capturing AI efficiency gains while protecting margin.
• M&A Dynamics: Businesses with embedded AI, proprietary workflows, and strategic counsel positioning are attracting strong investor appetite, with premium AI-embedded agencies commanding 8–12x EBITDA multiples.
